The American is to do the first practice session Friday morning at the Belgian Grand Prix Spa but the 23-year-old from Reigate will take over after that.

Chilton was removed from the cockpit on Thursday by team bosses citing “contractual issues”.

It is thought investors behind the British ace had not kept payments up to date but he was re-instated after the issue was resolved.

On Friday morning stewards issued a press release stating they had “received a request from Marussia to change the nominated driver Alexander Rossi (Car 42) back to their previously nominated driver Max Chilton (Car 4) in accordance with Article 19 of the regulations”.

Chilton released a statement on Thursday insisting he had “voluntarily” stepped out of the cockpit so the team could raise much needed finance.

The British racer set a record 25-race run without failing to finish a Grand Prix including 19 in his rookie year.

It ended when his teammate Jules Bianchi hit him at the Canadian Grand Prix in June.
